Realtime update of Android and iOS from web server?

Question

I'm trying to synchronise my android/ios app with the server.

My app allows user to update their profile and I would like to implement something like when user update their profile in the website, then user will get live update in their app or maybe a indicator like Facebook "New Stories" bar that allow user to touch and get their update.

I have read this SO Link but I wish I can know more in details or any alternative way on achieving this feature

I'd recommend that you check out NodeJS (http://nodejs.org/) and Socket.io (http://socket.io/) for your Use Case, though it might not be ideal for the mobile environment.
